Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
76 words
A heads-up display arrangement for a vehicle having a front window panel, and a radio receiver with an automatic tuning mechanism, comprising: a combiner arranged on the front window panel; a projector optically connected to said combiner, said projector projecting on said combiner a value provided thereto representing a frequency received by the radio receiver; and means for canceling provision of said value of frequency to said projector while the automatic tuning mechanism is in operation.
Claim 2
Dependent Claim
76 words
A heads-up display arrangement for a vehicle having a front window panel, and a radio receiver with an automatic tuning mechanism, comprising: a combiner arranged on the front window panel; a projector optically connected to said combiner, said projector projecting on said combiner a value provided thereto representing a frequency received by the radio receiver; and means for canceling provision of said value of frequency to said projector while the automatic tuning mechanism is in operation.
Claim 3
Dependent Claim
36 words
A heads-up display arrangement as claimed in claim 1, wherein said combiner includes a metallic oxide coating having a light transmittance smaller than that of the front window panel for a light having a predetermined wavelength.
Claim 4
Independent Claim
72 words
A method of controlling a heads-up display arrangement for a vehicle having a radio receiver with an automatic tuning mechanism, the heads-up display including a projector, the method comprising the steps of: providing to the projector for display a value of frequency received by the radio receiver while the automatic tuning mechanism is not in operation, and canceling display of a value of frequency while the automatic tuning mechanism is in operation.
Claim 5
Independent Claim
72 words
A method of controlling a heads-up display arrangement for a vehicle having a radio receiver with an automatic tuning mechanism, the heads-up display including a projector, the method comprising the steps of: providing to the projector for display a value of frequency received by the radio receiver while the automatic tuning mechanism is not in operation, and canceling display of a value of frequency while the automatic tuning mechanism is in operation.
Claim 6
Dependent Claim
121 words
In an automotive vehicle having a front window panel, and an instrument panel: a radio receiver with an automatic tuning mechanism arranged within the instrument panel; a combiner arranged on the front window panel; a projector optically connected to said combiner, said projector projecting a value of frequency received by said radio receiver, and a microcomputer connected to said radio receiver and said projector, said microcomputer executing a control sequence controlling said projector, said microcomputer including: means for providing to said projector said value of frequency received by said radio receiver while said automatic tuning mechanism is not in operation; and means for canceling provision to said projector of said value of frequency while the automatic tuning mechanism is in operation.
Claim 7
Dependent Claim
121 words
In an automotive vehicle having a front window panel, and an instrument panel: a radio receiver with an automatic tuning mechanism arranged within the instrument panel; a combiner arranged on the front window panel; a projector optically connected to said combiner, said projector projecting a value of frequency received by said radio receiver, and a microcomputer connected to said radio receiver and said projector, said microcomputer executing a control sequence controlling said projector, said microcomputer including: means for providing to said projector said value of frequency received by said radio receiver while said automatic tuning mechanism is not in operation; and means for canceling provision to said projector of said value of frequency while the automatic tuning mechanism is in operation.
